Welcome to GrahamTek



GrahamTek is an international company actively involved in the development, commercialization, manufacturing, marketing, selling and distribution of its technology in Desalination and Filtration with advanced products for the treatment of water.


 Assembly of 16" RO

A short History of GrahamTek
GrahamTek Systems , a South African privately owned company in alliance with GrahamTek Singapore Pte Ltd, forms a joint international group that devotes its efforts to the development and provision of clean and healthy water to the world.

GrahamTek has been actively involved in the market since 1998 in manufacturing, marketing and distribution of innovative environmentally friendly, almost chemical free and energy efficient Filtration and Desalination Water treatment systems . These are capable of providing world markets with affordable, high quality water, via technology that outperforms conventional membrane separation systems.

GrahamTek™ has successfully developed its global market by formation of strategic alliances which have assisted the company in establishing infrastructure that respond to the global demand for the needs of water in a professional and effective way.


An Introduction to GrahamTek Technology
GrahamTek 16 Inch Spiral Wound RO Technology

The GrahamTek RO System is a total rethinking of RO technology. The hydraulic conditions are vastly improved, and the sustainable flux is greatly increased. This means lower investment (CAPEX), reduced operating costs (OPEX) and smaller environmental impact due to lower use of chemicals.

These effects are achieved by:
The use of 16 inch diameter elements
Vastly optimized hydraulic conditions
Max. 4 elements per pressure vessel
An approximately 2:1 pressure vessel array
A unique equipment design

The combined effect of these parameters and devices allows operation of the system at extremely high fluxes, most often at least 50% higher and in some cases up to 150% higher than for conventional 8 inch RO technology. more ...


The next wave in RO Technology
A Consortium of leading RO membrane manufacturers and suppliers in the last 2 years, have, as a result of their joint cooperation into future advances in RO technology, recommended that the future industry standard optimal membrane size should be a 16-inch diameter element. This was the unanimous conclusion reached by the Consortium as a result of extensive field testing and consideration of economic and financial imperatives.

The Consortium recommendations were presented in 2005-2006. The key summary findings are presented here in the attached pdf file and are reprinted with the permission of "Water Desalination Report and Global Water Intelligence". They are also available as a hard copy in the IDA Desalination Yearbook 2006-2007.

For some years prior to the establishment of this Consortium GrahamTek had already chosen "16-inch" as the likely most optimal size to achieve more cost effective results in water treatment. GrahamTek's technology has therefore always been based on, and developed with, 16-inch diameter membranes as the base unit of RO operation. The findings of the Consortium (which did not include GrahamTek) have confirmed GrahamTek's belief in the viability of a 16-inch based system

GrahamTek R & D Team
In a meeting held in Singapore in April 2006, the GrahamTek Scientific Program was initiated. The objective of the Program is not to prove that GrahamTek technology works, but,
a) to demonstrate conclusively why it works so well;
b) simultaneously explore optimizing the various elements of the technology.
